40/70 window

The 40/70 window is a term that describes a time of day that's usually between 4:00pm and 7:00pm. During this time, lots of people are coming home from work or school, getting ready for dinner, or just relaxing after a long day.

Why is it called the 40/70 window? Well, it's because those are the temperatures that are recommended for indoor heating and cooling! When it's colder than 40 degrees Fahrenheit outside, it's a good idea to turn up the heat to stay warm. And when it's hotter than 70 degrees Fahrenheit outside, it's a good idea to turn on the air conditioning to stay cool.

But the 40/70 window isn't just about temperature - it's also about how people spend their time during this period of the day. Many families use this time to catch up with each other, have dinner together, or just relax and unwind after a busy day. Some people might watch TV, read a book, or play games with their family or friends.

Overall, the 40/70 window is a time of day that's important for staying comfortable and spending time with loved ones. Whether you're heating up some soup on a chilly evening or enjoying a cold drink on a hot day, make sure to take advantage of this special time and enjoy the company of those around you.
